Slide for soil stabilization techniques

1. Soil Stabilization
Techniques

2. Site feasibility study for geotechnical
projects is of far most beneficial before
a project can take off.
Site survey usually takes place before
the design process begins in order to
understand the characteristics of
subsoil upon which the decision on
location of the project can be made.

3. Stabilization methods fall into two
broad categories namely:-
- Mechanical stabilization
- Chemical stabilization

4. Mechanical stabilization :-
Under this category, soil stabilization
can be achieved through physical
process by altering the physical nature
of native soil particles by either
induced vibration or compaction.

5. Chemical stabilization
Under this category, soil stabilization
depends mainly on chemical reactions
between stabilizer (cementitious
material) and soil minerals (pozzolanic
materials) to achieve the desired effect.

6. Most of stabilization has to be undertaken
in soft soils in order to achieve desirable
engineering properties.
 A clay soil compared to others has a large
surface area due to flat and elongated
particle shapes. On the other hand, silty
materials can be sensitive to small change
in moisture and, therefore, may prove
difficult during stabilization.
